• a lower apparent weight

• the same apparent weight

• a higher apparent weight

• a lower or higher apparent weight depending on their speed

What is CONSTANT in uniform circular motion?

• speed

• velocity

• tangential acceleration

• tension

What is CHANGING in uniform circular motion?

• speed

• tension

Where does the force of gravity always point?

• perpendicular to a surface

• straight down

• tangent to a curve (touch it at only one point)

• along a rope/wire

The amount of time it takes for an object to return to the same position (complete one revolution) is its

• tangential velocity

• tangential acceleration

• centripetal acceleration

• period

Where do velocity vectors always point when an object experiences circular motion?

• perpendicular to a surface

• straight down

• tangent to a curve (touch it at only one point)

• along a rope/wire

Acceleration directed toward the center of a circular path is

• tangential velocity

• tangential acceleration

• centripetal acceleration

• period

What affects the speed at which an object moves if it is traveling in a vertical circle?

• tension
